Bayern Munich star Joshua Kimmich has questioned Germany’s mentality after their shock 1-0 defeat to Mexico on Sunday, according to Goal.com.
Kimmich said: "The mentality when facing a match of this level also counts, quality is not enough. We lacked that too, so many mistakes were made.
"Removing Saudi Arabia we have not won the last six games. You cannot compare the friendlies, in which the opponent does not press you as much as a qualifying round or a World Cup.
"The coach [Joachim Low] is right when he said that we lost a lot of balls. Mexico did well on the counter-attack, especially - they caught us several times."
